The openmp derivation provides both libomp and libompv. To avoid
accidentally linking with the wrong library and to avoid the nosv
dependency on libomp, this patch separates each version in a different
derivation.
Also, it adapts the clang wrappers and stdenvs to provide an stdenv per
openmp library where each openmp will be used by default when the
compiler flag "-fopenmp" is used. This eases linking ompv with nixpkgs
libraries, such as blis, that expect openmp to be provided with stdenv.

For now, we keep dontStrip for packages that already had it for systems
without the separatedebuginfo support.

This is needed since nosv must appear as a 1rst level dependency on the
final executable. Clang will add the dependency as long as it knows
where to find nosv (and nodes is used).
